In the present work, the effect of using four types of nanofluid including alumina/water, titania/water, silver/water, and copper/water, in volume concentrations of 1% to 4% within a shell and tube heat exchanger in three thermal loads has been investigated. This study is done based on investigating of 102 design cases concerning industrial experiences and Tubular Exchangers Manufacturer’s Association Standard (TEMA) requirements. The thermo physical properties of nanofluid have been taken as temperature dependent and calculated by use of proper valid experimental formulas. Most of the results show that using nanofluid will always cause enhancement in performance of heat exchanger and utilizing it in shell side is preferable, regardless of size of heat exchanger.
